Steps to reproduce:
1. Switch to English UI;
2. On sidebar, click on "Slide Transition" pane.
3. Within the slide transition sidebar window, click the "sound" list box. Observe that there are many sounds in the list.
4. Switch to any non-English UI and do the same as above. You will notice that only "No Sound; Stop Previous Sound; Other Sounds..." are in the list.
Current behaviour: (see the steps above).
Expected: All the sounds in step 3 of english UI are included in non-english UI at step 4.
OS and Version:
Ubuntu 14.04 x86
Version 4.3.0.1, 4.2.5.2.
"FirasH" says it's also reproducible in 4.1.6.2.
More info:
I see from pootle:
/ LibreOffice 4.3 – UI / sd/uiconfig/simpress/ui.po
slidetransitionspanel.ui sound_list 0 stringlist.text
(Only "No Sound; Stop Previous Sound; Other Sounds..." are translatable. All other sound items are not shown in pootle.

(In reply to comment #8)
> suokunlong: no, they'll just appear with the patch.
So, I assume:
* With this patch, all the sound list items will appear in both english and non-english UI.
* Athrough they will appear in non-english UI, they are not translated (they are in english when in non-english UI).
Am I correct? If so, I believe we should make these sound names translatable. So maybe another patch is needed?
